When in doubt, keep it safe and as @DLane said, “Keep it Simple”. Your troubleshooting will be easier with each on on its own master and flow sensor.
Let us know how it turns out. There are others reading this that can benefit from the comments here.

It turns out the line out of the backflow is 1 1/4” PVC pipe. What do you all recommend for the type of master valves and couplings to use?
Does it make sense to go from the backflow’s 1 1/4" PVC -> 1 1/4" T -> (two branches) 1 1/4" PVC -> 1 1/2" PVC Master -> 1" PVC (6 inches) -> Rachio WFS -> 1" PVC (6 inches) -> 1 1/4" PVC -> T (two branches combine) -> 1 1/4" PVC (master line).
Any suggestions or criticisms there?
Thanks in advance
That may be a feasable connection. I would give a little bit more length after the WFS to get better accuracy.

@franz , @emil ,
I have finally installed my WFM’s. See pictures. I installed valves to bypass the WFM’s if needed. I am using 3 master valves, 3 WFM’s. Pairing went very smoothly. WFM’s bypassed right now. I have I question, how do you winterize the WFM’s?

That turned out pretty nice. Way to go and nice looking work.

Thanks!
Do you know how to winterize the WFM’s?

I only gave myself 16" before and 8" of 1" pipe not including the connections and WFM. Do you think I have compromised the accuracy of the WFM. I can always add two more boxes after the WFM to give me an additional 24" of length. You thoughts.
Hey @jsore !
No need to winterize your Wireless Flow Meter. It will stay in place during winterization, blowouts, and system maintenance.
As long as you have 14" of straight pipe between the backflow preventer and the valve box, you will be just fine.

Should I place insulating material in the valve box holding the WFM’s. I do blowout my system every fall.
How do i handle the controllers, turn them off, un-plug them or what?
Maybe a winterization article is in order.

Great questions, @jsore !
Here is one article on some winterization basics .
There’s also some great winterization advice from @robertokc here and a great winterization site using the Rachio API from @schaeferb .
Hopefully all of this can help!
